Having all the plugins to date, is a sign that your computer will work well and by the way, we have a more secure and stable. Mozilla already had a tool called Plugin Check, which will alert users of its Firefox browser, for when they had new versions of Flash, DivX, Java, QuickTime, among others.

But being a tool that helps us have a safer computer, Mozilla opens the doors to other browsers such as Opera 10.5, Safari 4, Chrome 4 and Internet Explorer either version 7 or 8.

Once you get into the tool, start the search and verification of the installed versions. Let you know whether you're a day or you need to update, in which case we will provide a button from which we sent to the download page, so that everything is as simple as possible.

One of the advantages of using the Google browser, Chrome, is that having separate processos each tab, if one of the pages that YOU will give you error, will not make the whole browser hangs, a feature that Apple's browser anela , Safari, using both its computers under Mac OS and Windows computer.

But one of his employees, Anders Carlsson, development manager and the Safari Webkit engine, today announced it is working on a new framework called Webkit2, which will seek to isolate all operations in the style of Chrome, but with a difference concerning the policy pursued by Google and that this feature will make the browser much more stable and more user friendly, is that the implemented directly on the motor and may be used by other companies on their products.

Nobody will seem strange to read that sometimes Firefox is slower than other browsers (compared for example with Google Chrome). The slowness of Firefox can be seen in several parameters, one of them is for example the JavaScript engine, which is responsible for recognizing and interpreting the JS code is in web pages.

This is a very important part of the browser, and is used as parameter when doing benchmarks (performance tests).
Today Firefox is behind Chrome, Opera and Safari in performance when doing basic tasks with JavaScript code.

The Mozilla browser has nanojit as motor (in fact this project was developed by Adobe to interpret ActionScript in Flash. It is also open source since 2006), which has a regular performance.

The new engine called JägerMonkey, will nanojit parts, however their main base and more solid will be formed with pieces of code from Apple Webkit project in an attempt to make Firefox more about their competitors, especially when running JavaScript code.

This new heart for Firefox is at a very early stage of development and still not be distributed widely. For developers, there is a place where you can download the source code and also check the status of the project.
